Living off the Air

Written by Science Knowledge on 10:51 PM

Aeroponics—cultivating plants without soil or water—started to take off in 1983 when Rick Stonerof Agrillouse, a company in Berthoud, Colorado, patented a water-conserving, pesticide-free way to grow crops. NASA chipped in funding for application to potential future space colonies. The colonies are still beyond the horizon, but commercial production of air-grown veggies is becoming a reality. Optometrist La, Forrest of Frederick, Colorado, has expanded his aeroponic greenhouse to about 150 square meters, which may make him the world's largest aeroponicfarmer. His company, Crow Anywhere Air-Foods, grows tiny seedlings of mesclun and other greensfor restaurants; misting their roots with a nitrogen and calcium rich spray every 20 minutes. Forrest's equipment involves several thousand nozzles, pipes, and other parts. But he says he is working on a simpler, cheaper 500-part system to sell to like-minded growers.

This is the first I've seen someone else trying to make a go of it, says (Award Harwood, who patented an aeroponic system with a cloth conveyer belt but couldn't make it pay. As far as the U.S. growers know, the technique hasn't caught on anywhere else in the world. But Stoner sees a big potential: The technology can be set up anywhere, including Iceland or Antarctica, he says.

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
